Users can download the app for free from the App Store or Google Play, to scan the coin with their camera. They can also link the app to their social media to share what they find in their pockets and wallets.

There is also a heat map within the app, showing where different coins are being found and directing them to swap shops where they can trade coins with fellow collectors. Users can also use the app to have a go at designing their own coin.

Anne Jessopp, chief executive at the Royal Mint, said: "These designs were selected because we feel they represent a diverse mix of elements that make up the country we all love.

"There is a lot to be proud of in the UK - whether it's at the highest level, our Houses of Parliament representing democracy and freedom of speech, technological advancements such as Tim Berners-Lee's world wide web, or just a good cup of tea, it's all here in the designs.

"We hope the British public is inspired to take part in the great British coin hunt by checking their change for those miniature works of art that spell out just some of the many iconic themes that are quintessentially British."
